Forty-year old American artist and teacher Joe Blaustein was in Florence on November 4, 1966 when the Arno submerged the city. With his camera in tow he decided to document what was happening in real time.
Among the very few colour photos of the 1966 Florence flood, the images are now on show at an exhibition at the Italian Cultural Institute of New York (686 Park Avenue, free admission, 6-8pm, until November 23, 2016).
